ABSTRACT:
An improvement for a low frictional connection between a first element and a second element wherein one of the elements rotates with respect to the other, such as a crankshaft and a connecting rod, includes the addition of a helical member located between the elements. One of the elements i.e., a crankshaft, would include a convex journal surface and the other element i.e., a connecting rod, would include a concave receptacle surface. The helical member is located around the journal surface. A bearing is positioned between the two elements directly adjacent to the helical member and moves against the helical member. The helical member is capable of being hardened and/or machined such that it presents a low frictional surface for the bearing to move against. Since the helical member is not an integral part of either of the elements it is capable of being replaced such that catastrophic marring of its low frictional surface either during manufacture or use does not require replacement of one of the elements but only requires replacement of the helical member.
